Ported All Pro heads w/ Jesel rockers setup for solid roller All-pro cathedral port heads and Jesel J2k rockers.
Ported by Dwayne Welder (ex-katech employee)
2.055 Ti intake 30° back angle
1.600 Ferrera Inconel Exhaust
Flowed on a superflow 600 at 28 in" 4.070 bore
Don't know exact port volume, but i know they started fairly large.
These were ported knowing it was to be a turbo motor.
The hard parts.
Jesel J2k rocker system 1.7 ratio
Ferrera valves: 2.055/1.600 Ti/In
Comp 26097-16 Springs: Installed at 1.88" - 265 seat/625 at .700/bind at 1.135"
Comp Ti retainers 732-16
Manely locks: 13152-8 on the ex, 13151-8 (+.050) on the in
Comp spring locators 4781-16
New valve seals.
Heads are cut for correct geometry on the rocker stands. Valve cover rail clearanced for the rockers. Clearanced for 3/8" pushrods.
Chambers are 61cc
All parts are new, never run. They are installed on the long block at the moment, but that's the extent of use.
I don't want to seperate the heads and rockers.
